Close friend Leon ten Voorde is confident Erik ten Hag will win over the Manchester United dressing room.
The Ajax coach is expected to be confirmed new United manager in the coming days.
Ten Voorde has known Ten Hag since they were four years of age and told the Manchester Evening News: "You never read or hear players talk negatively about the trainer Ten Hag.
"One of his qualities is managing a dressing room. He can also handle the so-called difficult characters. He has always had those guys in line and they are all positive. Also at Ajax, he first had to overcome scepticism but in the end, he succeeds.
"He is clearly the boss, but at the same time also social and knows everything about the players. And no one knows if the locker room will be toxic next season as well. Wait and see what will happen in the transfer area."
He also said: "Where Erik works, he always has an important voice in a lot. He is never just a trainer.
"He is a trainer who clearly knows what he wants. He never lets himself be led by the outside world and imperturbably goes his own way.
"My personal opinion: When United come after four-and-a-half years of Ajax, you don't say no easily. Moreover, such a job is tailor-made for him. Building a club.
"He likes attacking football, and players who fit into it. He always looks at the material and adjusts the playing style accordingly. He played differently at FC Utrecht than at Ajax."
